Description

lighttpd seems to crash. Issue exists in 1.4.18, 1.4.19 (.18 seems to survive longer though)

<f'stbuehler> if there is more than one fcgi-package in one chunk, that will happen

<f'stbuehler> NovaKing: i guess php send two "fastcgi-packets" and lighty read them into one chunk

attached are different types of traces.

It seems gdb gave a broken backtrace; with -O0 we had a cleaner backtrace which indicated a normal out of memory problem, as there were many big files sent with fastcgi without using x-sendfile.

ATM lighttpd-1.4.x does not support ranged requests with x-sendfile from fastcgi but lighttpd-1.5.x should, so this may be an alternative.
